The 2016 model has already been spotted testing in the Arctic Circle ahead of its launch. The disguised prototype suggests that exterior tweaks on the hatchback are minimal.
Alterations are focused on the front of the car, where the refreshed design carries subtle cues from the forthcoming Giulia, which is also due an update. The front bumper gets a revised design, and camouflaged light clusters hint at some changes.
The rear lights remain the same as those of the current car, while a camouflaged interior on a test mule spotted late last year suggests that upgrades in the cabin should be expected.
There's no official confirmation yet of how the engine line-up may change, but more efficient versions of the familiar T-Jet petrol and Multijet diesel units are likely to replace the current crop of powerplants.
First launched in 2010, the Giulietta is priced between £18,450 and £27,590 and counts the Vauxhall Astra and Volkswagen Golf among its rivals in its class. There's no official word from Alfa Romeo on whether this facelift will command a price increase.
